Stanley J. Grenz in his Millennial Maze writes,

The contemporary discussion of eschatology among evangelicals, fueled as it is by questions surrounding the significance of the vision of Revelation 20, ought not to be dismissed as being of no consequence to the Christian faith. On the contrary, by considering the question of millennialism, evangelicals are engaged in a debate concerning the climax of human history, understood in terms of God’s intention for creation. In so doing , the parties to the discussion are probing a theme crucial to the biblical message, the euangelion (gospel), the proclamation of which evangelicals have always seen as central to the Christan mandate in the world.
The anticipation of a climax to human history — a corporate eschatology — and the resultant question concerning the millennium as a specific stage in that climax cannot be relegated to the fringes of the biblical proclamation. On the contrary, it belongs to the heart of what the Bible intends to teach (p. 27).
